Tahiti acid lime is an important citrus crop in Brazil. Some viroids reduce citrus tree growth on different rrotstocks and may be used for tree size control animed at the establishment of orchards with close spacing that can provide higher productivity than conventional ones. To study the effects of citrus viroids inoculation on vegetative growth, yield and fruit quality of 'Tahiti' acid lime [Citrus latifolia (Yu. Tanaka) Tanaka] grafted on six rootstocks (main treatments): 'FCAV' and 'Rubidoux' trifoliate orange cultivars [Poncirus trifoliata (L.) Raf.], 'FCAV' and 'Limeira' Rangpur lime cultivars [Citrus limonia Osbeck], 'Carrizo' citrange [C. sinensis (L.) Osbeck x Poncirus trifoliata (L.) Raf.] and 'Sunki' mandarin [Citrus sunki Hort. ex Tanaka] and inoculated with three viroids isolates (secondary treatments): [Citrus Exocortis Viroid (CEVd) + Hop stunt viroid (HSVd - CVd-II, a non cachexia variant) + Citrus III viroid (CVd-III), [Hop stunt viroid (HSVd - CVd-II, a non cachexia variant) + Citrus III viroid (CVd-III)] and control [no inoculation], an experiment was set up in February 2001, in Bebedouro, São Paulo State, Brazil. The experimental design was a split plot design in randomized blocks with six main treatments (rootstocks) and three secondary ones (viroid inoculation) with three plants per plot and one per subplot. Inoculation was made at field ten months after planting by bud grafting. The trifoliate oranges rootstocks induced less vigor. Both isolates reduced tree growth (plant height, canopy diameter and volume). Trees not inoculated yielded better (total fo four harvests) than inoculated ones but the productivity (Kg/m³) was the same in the three harvests. Total soluble solids were higher in fruits of trees inoculated with the CEVd isolate and acidity was higher in both viroids treatments. No interaction between rootstocks and isolates occurred for drought tolerance. Rangpur lime clones and Sunki mandarin trees were the most tolerant to drought. Trees inoculated with the CEVd isolate were more susceptible to water stress than control ones, independently of the rootstock.

This experiment was carried out with the objectives of determining repeatability coefficients, the number of harvests necessary to increase accuracy and the genotypic stability of yield characteristics in Brachiaria brizantha cultivars in the northeast region of Brazil in the period from July 2009 to March 2011. The experimental design used was completely randomized with three treatments (Brachiaria brizantha var. Marandu, Xaraés and Piatã) and three replications. Each plot was harvested seven times: five in the rainy season and two in the dry season. Immediately after each harvest, the forage was weighed and dried to obtain total, stem, leaf and dead dry matter yields. For the estimation of the repeatability coefficient, analysis of variance, principal components (correlation and covariance matrices) and structural analyses were used. The repeatability coefficients (r) obtained by the different methods, for all characteristics evaluated, varied from 0.009 to 0.837. The estimates of the repeatability coefficients obtained for all characteristics evaluated by the method of analyses of variance were almost always lower than those obtained by the other methods. By the principal components method (based on the covariance matrix), the estimates were always higher than those from other methods. Considering that levels of 80 or 90% confidence are satisfactory in the evaluation of the relative superiority of the cultivars for all the evaluated characteristics, with the exception of dead matter yield, the seven harvests are sufficient for the choice of the best cultivar to be used in the northeast region of Brazil.
